SIGNATURE-PRESS.

SPECIFICATION forming part of Letters Patent No. 394,977, dated December 25, 1888.

Application filed September 3, 1887. Serial No.248,669. (No model.)

To aZZ whmn it may concern.-

Be' it known that I, RUSSELL A. HART, a citizen of the United States, residing at Bat tle Creek, county of Calhoun, State ,of Michigan, have invented a new and useful Signature-Press, of which the following is a specification.

The objects of this invention will appear in the following description and claims.

One prominentobject which may be mentioned is a construction and arrangement of parts whereby the press automatically-stops when the bundle of printed pages is sufficiently compressed.

Another leading object consists in constructing the tray in which the pages are placed and the blocks between which the pages are compressed so that the bundle of pages after being compressed can be readily tied with a strand of cord on each of the four sides and crossed at each end, and this while the compressed bundle is still in the press.

In the drawings forminga part of this specification, Figure 1 isa side elevation with parts removed, below described; Fig. 2, a plan; Fig. 3, end view of parts shown in Fig. 1, looking from a point at the left. Fig. 4 is a detail view, in elevation, from the same point of observation. Fig. 5 is a transverse section on line 13 p in Fig.1. Fig. 6 is a detail view, in crosssection, of elements y, u, and r in Fig. 5 on line 10 20. Fig. 7 is a perspective view of a supplemental tray, hereinafter described; Fig. 8, a section on line 2 2, Fig. 1, looking from a point at the right; and Figs. 9 and 10 are enlarged views, in perspective, of blocks C and C, and Fig. 11 of frame A, shaft :20, and plate 2', all in Fig. 1.

Referring to the lettered parts of the drawin gs, A is a V shaped tray supported by standards T, these parts constituting a part of the frame A, in which the internally-threaded shaft 05, with internal screw, 0, is supported. The tray A has slots 0 0 through each of its oblique sides and a V- slot, f, through one end, Fig. 3. The screw 0 has a head, 0, against which the block 0 is placed cornerwise inthe tray A. The block C is placed in the other end of the tray A. In Fig. 7 is shown a supplemental V-tray having one closed end and slots in the oblique sides, which slots register with the slots 0 c in the main tray A. The printed leaves are placed on their edge cornerwise in the supplemental tray, Fig. 7, and the latter is placed with its contents in the tray A. The blocks 0 C are placed at the ends of the bundle of leaves in the supplemental tray. One of the pulleys B is then slid on the shaft 00 to engage with the dog at by swinging the lever L.

The arrangement of the pulleys B, which revolve in opposite directions, and the dog at and screw 0 are not new, per 88, and will be understood without details being given. Suffice it to say that when one of the pulleys engages the dog the screw 0 moves forward tov ward the left, as here shown, and when the other pulley engages the dog the screw moves back. When the screw moves forward, the leaves are compressed, the block 0 being carried along, as indicated by the dotted position in Fig. 1.

hen sufficient pressure is brought to bear, the block C presses hard enough against the spring-actuated slide on to force it against the upper end of the pivoted lever F. This action moves the rod t, which is attached to the lower end of lever F and the lower end of the pivoted lever U, which operates the lefthand-pulley, and of course said pulley is by that means slid away from the dog n and the screw thus automatically stopped. The supplemental tray is also slid along and its open end extends out through the slot f of the tray A and through the opening in top of lever .F, Fig. 4, this slot and opening being made purposely to accommodate the supplementaltray. The sliding action of this tray is not illustrated, but will be understood, as the head 0 of the screw 0 slides it and the block 0 along at the same time; but the supplemental tray may be dispensed with, if desired, and the leaves be placed directly in the tray A.

The blocks 0 O are so constructed on their inner faces (one having transverse grooves e 6, Fig. 9, and the other a three-cornered mortise, e, each corner opening through the edge of the block, and a groove, J, leading from the other edge of the block into the mortise or recess e, Fig. 10) that by the use of a large needle the compressed bundle can be tied with a cord, so there will be a strand on each of the' four sides of the bundle and crossing at the ends, the same as a package can be tied when held in the hands. 13 y this means when the screw 0 is run back releasing the bundle itis ready to be taken out of the press, and is firmly held in its compressed condition.

The plan of tying is not here illustrated, but the following will make it clear. A loop is made in one end of the cord and caught over a stud or the like to hold it. The other end is put through one of the channels of block C, thence along one of the oblique sides of the bundle, and then passed obliquely through the recess 6 of block (P-as, for instance, from 1 to 2. At 2 the cord is caught over a stud, (not shown,) from thence along the second side of the bundle and through the other groove of block C, back along the third side of the bundle and through groove J, and up through the loop which was left at 2, and thence from to 3 and along the fourth side of the bundle to the place of starting. The cord is then caught through the first-named loop, and then by releasing the loop at 2 and drawing the cord tight and tying it the bundle is bound at the sides and ends, as before stated. The recess e, Fig.1 0, allows the loop,which was at 2, to be drawn to the center of the end of the bundle. The crossed cord in Fig. 8 shows the appearance atthis end of the bundleleft-hand end in Fig. 1.

The lever L, Fig. 5, is pivoted to a bracket, 3 which bracket is attached to the frame in Fig. 1, but is not shown in said latter-named figure. The lever L engages a lug, i", and as the other end of said lever enters the groove a of one of the pulleys, the left pulley is locked in proper position to move the screw 0 forward. '11 is a sliding wedge, Figs. 1 and 5, to which a rod, S, is attached. The other end of rod is attached to the upper end of the ccntrally-pivoted lever (I, and the lower end of this lever is attached to the rod 2. By this means when the end. lever, F, operates by the pressure of the block 0 on the slide on the wedge is drawn forward, pressing down on the end of the lever I, Fig. Thislever is shown 1. At .2, Fig. 5, is a in cros spring-actuated plunger, which is carried upward by the leverl when the wedge 14- tilts said lever, and this raises the lever ll, unlocking it from the lug S, so that the lever 0 can slide the lefthand pulley B out of engagement with the dog a. The lever L is shown clearly in the plan in Fig. 2. The head 0 of the screw has a projection, to, through the slot 0 of the tray A. Should the screw 0 be started by accident or meddlesome design when the projection to comes in contact with the head 1; of the rod r, Fig. l, the wedge a, to which said rod is attached, will be drawn forward, unloekin the lever L, and as the rod S is also attached to the wedge the lever r (by means of the hereinbefore-described construction) will be tilted and the movement of the screw (1 will be automatically stopped.

It should have been stated that the registering elongated slots in the oblique sides of the two trays enables the cord-needle to be inserted into the grooves of the blocks (1 as before explained.

In Fig. 11. I have shown a broken portion of the frame A and the shaft: :1: in perspective, showing also grooves S in the shaft .1, near the bearing into which groove a semicircular plate, .2, is inserted edgewisc beneath the shaft, and is secured to the face of the bearing, which in Fig. 11 is the end of the frame A. The object of this plate is to keep theoil from unduly running out of the bearings. ()ne of these plates maybe employed on each side, and they may be at each end of the shaft, or, rather, at each bearing of the shaft.

The screw is automatically stopped from running too far back by means of a slidin bar, 1", Fig. l, right-angled at each end. One end enters the groove a of the right-hand pulley ll, and the other end. passesup through a slot in the tray A to etmtaet with the head 0 ol. the screw, which contact throws the pulley to the right, disengaging it from the dog 9?.

llaving thus described my invention, what I claim is- 1.. The comlnnation ot' the main tray havin g the slotted sides with. the blocks having crossin g-grooves in on e and the three-cornered recess and the groovein the other, an d means for compressing the bundle between said blocks, substantially as set forth.

2. The combination of the main tray having the side slots and the V end slot, the slotted supplemental tray, the grooved and recessed blocks for placing at the ends of the bundle in the latter-mulled tray, and means for compressing the bundle between the blocks, substantially as set forth.
